Extended overlap-save and overlap-add convolution algorithms for real signal
Jagdish D. Kene · 2007
The modified overlaps save and overlap adds algorithms for filtering real signals by an N tap FIR filter are introduced. These algorithms compute two N sample output blocks simultaneously at every processing step using 2 N point transforms while the traditional methods compute only one N sample block with the same length transforms. They achieve streamline processing for additional delay of N samples.
